Chopard
Classic Racing 168511-3018— lug 20mm

The Chopard Classic Racing 168511-3018 features a lug width of 20 millimetres, which is the contemporary standard for sports chronographs of this case size. The measurement corresponds to the distance between the two metal lugs of the watch at the strap attachment points.

There is no single definitive choice, but rather functional alternatives that align with the racing identity of the model. Genuine black alligator imparts refined sportiness; vegetable-tanned calf develops a natural patina over time; vulcanised rubber maximises visual proportion with the 42mm case; shell cordovan offers exceptional longevity and intense lustre from artisanal workmanship. Selection depends on your primary context of use.

The strap is changed by extracting the spring bars—the small metal pins that connect the strap to the case lugs. Using a spring bar tool, apply gentle pressure to one of the two pins to create a release gap, allowing the strap to slide upwards. The operation requires caution to avoid scratching the stainless steel case.

Yes, all straps with a 20mm lug width are compatible with the Chopard Classic Racing 168511-3018. You can choose from alligator, calf, shell cordovan, rubber, suede leather, and other artisanal materials, provided that the ends fit properly to the case lugs.

Longevity depends on material quality, environmental wear, and rotation frequency. A quality artisanal vegetable-tanned calf strap lasts 3–5 years with regular use. Shell cordovan can exceed 7–8 years. Alligator straps, if not exposed to excessive moisture, maintain structural integrity for 4–6 years. Prolonged exposure to rain significantly shortens lifespan.
